Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

List of Artifact Collectors

A number of collectors of computer artifacts have contacted the Charles Babbage Institute (CBI)
and expressed a desire to exchange information with other collectors. In response to this need,
CBI will undertake to complete a list of private collectors to be made available to interested
persons. If you wish to be included in such a list, please send your name, address, and
telephone number to the CBI archivist. It would also be helpful to include a one-sentence
description of your collecting objectives. If enough individuals respond, CBI will maintain the list
and distribute it upon request. Information or inquiries should be directed to the archivist.

The Second ACM SIGPLAN History of Programming Languages Conference
(HOPL-II)

On April 20-23.1993. the second ACM SIGPLAN History of Programming Languages
Conference (HOPL-II) will be held in Cambridge, Mass. In 1978, the first History of
Programming Languages Conference presented the development and evolution of 13
languages, HOPL-II the people who participated in that work, and the context in which it was
undertaken. Much has happened since the first HOPL conference, and HOPI-II will address the
history of those significant developments. In addition to histories of specific languages, HOPI-II
also expects papers on histories of language features and concepts, and histories of classes of
languages related by language paradigm or application area.

Taking a historical view can be surprising and illuminating. From the present, it seems easy to
look back at the development of a computer programming language; to criticize. compliment,
contemplate, and categorize; to decide what is great and what is small. Yet it is also easy to
misconstrue and misunderstand. The development of a programming language takes place in a
context of goals, constraints, and assumptions. People, including the language developers
themselves. are often unaware of this historical context.

Developers of five important languages have accepted invitations to tell their stories at HOPI-II
Bill Whitaker on Ada. Dennis Ritchie on C, Niklaus Wirth on Pascal, Alain Colmerauer on
Prolog, and Alan Kay on Smalltalk. In addi...
